Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology, and further to the field of ironmaking equipment technology. Specifically, it relates to a rapid casting device for the main tapping channel of a blast furnace that is simple in structure, easy to maintain, and reliable in operation. Background Technology

[0002] The blast furnace tapping trough is a crucial facility in front of the blast furnace. Its main function is to buffer the slag and iron ejected from the taphole, achieving separation of molten slag and iron, and further transporting the slag and iron separately to the ladle and slag granulation facilities. The working conditions of the blast furnace tapping trough are extremely harsh, with high temperatures and prolonged scouring by molten iron. Therefore, the structure and refractory casting of the blast furnace tapping trough are key factors in its service life and also affect the blast furnace's production efficiency. Currently, the casting methods and processes for the blast furnace tapping trough have the following shortcomings:

[0003] 1. After the main trough of the blast furnace is set up, the material is mixed with a mixer and then pushed to the pouring point by a wheelbarrow for manual pouring. The pouring efficiency is low, and each time it takes about 30 people to work continuously for 24 hours to complete the pouring.

[0004] 2. Due to the large number of people involved in the pouring process, the safety risks are relatively high in the gas-filled and confined space of the blast furnace tapping area.

[0005] 3. The crystallization time of refractory after casting affects the casting quality. Generally, the casting time should not exceed 12 hours, but the current casting time of refractory is too long, which affects the casting quality.

[0006] 4. The mixer discharge point is at the bottom, and some raw materials are not mixed evenly before being poured, which affects the quality of the pouring.

[0007] 5. The mixer uses manual water addition during the mixing process, resulting in uneven mixing of the refractory material.

[0008] 6. Manually using a shovel to "dig" open the material bag to release the material is not conducive to safety and even mixing.

[0009] 7. The mixer is not equipped with a lifting hole, which makes it difficult to lift and transport.

[0010] Therefore, researching and developing a rapid casting device for the main tapping channel of a blast furnace that is simple in structure, easy to maintain, and reliable in operation is the key to solving this problem. Utility Model Content

[0011] The purpose of this invention is to provide a rapid casting device for the main tapping channel of a blast furnace that is simple in structure, easy to maintain, and reliable in operation.

[0012] The purpose of this utility model is achieved as follows: it includes a steel rail, a translation trolley, a mixer, a variable-direction guide chute, a water spray device, a bag-breaking triangular knife, and lifting feet. The steel rail is set above the main tapping trough of the blast furnace; the translation trolley is set on the steel rail; the mixer and the water spray device are respectively set on the platform of the translation trolley; the variable-direction guide chute is set on the side of the mixer; the bag-breaking triangular knife is set on the top of the mixer; and one lifting foot is set at each of the four corners of the translation trolley.

[0013] This utility model consists of steel rails, a translation trolley, a mixer, a variable-direction guide chute, a water spraying device, a bag-breaking triangular blade, and lifting feet. The translation trolley is mounted on the steel rails, allowing the mixer to move flexibly above the main tapping trough of the blast furnace for flexible casting. The variable-direction guide chute can rotate within a 180° range, facilitating uniform mixing and flexible casting. A water spraying device is installed on the platform of the translation trolley to ensure uniform water spraying, uniform mixing, and consistent mixing quality. A bag-breaking triangular blade is installed on the top of the mixer to automatically break the raw material bags, ensuring even distribution of the material inside the mixer and eliminating the safety risks associated with manually breaking the bags. Lifting feet are installed at the corners of the translation trolley for flexible lifting.

[0014] This invention can effectively improve the mixing efficiency of the mixer and the pouring efficiency of the blast furnace tapping main channel, and the pouring quality of the blast furnace tapping main channel is high, while also improving the safety of on-site operations.

[0015] This utility model has a simple structure, is easy to maintain, works reliably, and can quickly cast the main tapping channel of a blast furnace. Attached Figure Description
